Ice nucleation of water droplet containing solid particles under weak ultrasonic vibration

“…For a two dimensional simulation, R-P equation is boundary sensitive [53] . Therefore, following [40] , [53] , the revised R-P equation is written as where is the computational domain size, is the bubble pressure, and is the pressure at the boundary. The revised R-P equation is solved using the 4th order Runger-Kutta integration algorithm.…”

“…The viscosity can then be given as . The surface tension is obtained by the Laplace law [40] . The comparison between the analytical solution and the simulation results is shown in Fig.…”

“…Therefore, the numerical approach becomes a powerful and useful tool for solving such problems at the small scale. Compared to traditional CFD methods [38] , [39] , LBM can deal with the mesoscopic fluid-fluid or fluid-solid interactions more conveniently [40] , [41] , [42] . LBM also has advantages of simplicity, high computational efficiency, and suitability for parallel computing.…”

Thermodynamic effect of single bubble near a rigid wall

“…In the recent years, significant progress in advanced flow simulation method has been made in understanding and modeling complex multiphase flows, especially for the thermodynamic effect of single bubble. Although Boundary Element Method (BEM) [15] , Smooth Particle Hydrodynamics (SPH) [16] , and Lattice Boltzmann Method (LBM) [17] have been applied in simulating bubble dynamics, the numerical simulation of investigating single bubble thermodynamics is a typical compressible problem, mainstreamedly realized by coupled solving the compressible Naiver-Stokes equations (N-S equation), phase equation, and interface capture model (like VOF and LS) [18] . Beig et al [19] applied the compressible N-S equation to simulate a single bubble inertially collapsing near a rigid surface to measure the temperatures produced in the fluid.…”

Growth and Collapse Dynamics of a Vapor Bubble near or at a Wall

“…Chen et al constructed a multiphase LBM flow model to study the process of the growth and departure of bubbles [26]. Yang et al investigated the thermodynamics of a collapsing cavitation bubble, analyzing the maximum temperature, velocity, and pressure field of a bubble near a wall [27].…”
